This is the second of two very similar images, both featuring illuminated views of the so-called “Rock of Ages” in the left foreground, and the Cave of the Winds, behind the falls in the background.
The description states:
NIAGARA FALLS BY ILLUMINATION
This new enhancement of America’s beauty resources is nothing more than the Falls, under flood lighting for four hours each night. Their own power has been taken from them, brought under the control of man, and then turned back upon the power creator itself, and we get a new beauty, ten-fold greater than any beauty known at the Falls before man took hold to conquer them for service.
–This image has more attention paid to the items in the foreground, showing more detail of the Rock of Ages while nearly omitting the wooden walkway in the background. This image shows the nearly identical viewpoint without color or artistic impression.
This image likely dates from the 1930s.
